2016-17 Field Test Version

The Decomposers unit builds on what students learned about organic and inorganic materials, how all systems exist at multiple scales, and transformation of materials and energy during chemical change in the Systems and Scale and Animals units. In the Decomposers unit students learn how the processes of digestion and biosynthesis transform food molecules into the biomass of an organism during growth, and how the process of cellular respiration transforms organic materials to inorganic materials and chemical energy to energy for function and movement of organisms.
